Abstract

We describe a 42-year-old man with very late stent thrombosis (VLST) 35 months after implantation of a sirolimus-eluting stent (SES). Three months after the VLST episode, a follow-up angiography showed a formation of peri-stent coronary artery aneurysm. Sixty-five months after SES implantation, the patient suffered an out-of-hospital cardiac arrest. We performed spasm provocation test using acetylcholine to evaluate coronary vasomotor response and the coronary segments adjacent to the SES showed significant vasoconstriction. Intracoronary pretreatment of Rho-kinase inhibitor, fasudil, markedly attenuated acetylcholine-induced vasoconstriction. This report documents a unique case suffering from multiple fatal complications after SES implantation.
